An inkjet recording ink comprising at least one magenta dye or cyan dye dissolved and/or dispersed in an aqueous medium, wherein a wavelength ( lambda max) at the maximum reflection density of the ink is in a specific wavelength range ( lambda ex) and a reflection density at the specific wavelength ( lambda er) longer than the lambda max is not more than x% of the maximum reflection density, the lambda ex is from 530 to 580 nm, lambda er is 600 nm and x is 50 in case of the magenta dye ink, and the lambda ex is from 580 to 630 nm, lambda er is 670 nm and x is 90 in case of the cyan dye ink. <??>An inkjet recording ink comprising at least one dye dissolved and/or dispersed in an aqueous medium, wherein the ink contains at least one betaine surfactant. <??>As the dye, a magenta dye having a specific azo structure and a cyan dye having a specific phthalocyanine structure are preferably used. <??>According to such constructions, an inkjet recording ink, which is excellent in ejection stability, provides an image having good hue, excellent preservability and high image quality and maintains the performances under sever conditions, and an inkjet recording method can be provided.
